Running Hadoop in Terminal Rooms

To setup a hadoop hadoop cluster in a terminal room, make sure you have booted some PC's with Ubuntu Linux 12.04. Write down the names of the PC's you want to use as slave nodes.
Then run tkhadoop.sh:

/usr/local/bin/tkhadoop.sh [slaves]

For example, when you're physically working with hg137pc01 and pc two and three are available and running linux, use:

tkhadoop.sh hg137pc02.science.ru.nl hg137pc03.science.ru.nl*

Be sure to use fully qualified domain names slave host names. This is required for kerberos based ssh authentication, used in this our script and the scripts that are bundled with hadoop.

This will setup the files needed to run a three nodes hadoop cluster. The host on which you execute tkhadoop will be the master node and will be used as slave as well.
You'll find your hadoop installation in:
